B RAKE ATTACHMENT FOR INK-ROLLERS.

SPECIFICATION forming part of LettersPatent No. 529,932, datedNovenl'ber27, 1894. Application filed December 28, 1893- Serial No. 494,930. (Nomodel.)

To (ZZZ whom it may concern.-

Be it known that I, EMIL MEIER, of the city, county, and State of NewYork, have invented a new and Improved Brake Attachment for Ink-Rollers,of which the following is a full, clear, and exact description.

lVIy invention relates to improvements in printing presses andparticularly to attachments for the ordinary angle or distributingrollers. These, as it is well known, are usually made of glue andmolasses, and have endwlse as well as rotary movement and are turned bycontact with the inking table. If riders are used on the angle rollers,the increased heft causes the rollers to be struck with too great forceby the table and they soon get out of shape, and if they are not used,the rollers, on account of their weight, turn freely after being struckby the table, so that when the table, on its return stroke, comesincontact with the rollers, it meets them while the rollers are turning inthe reverse direc tion to the movement ofthe table, and injuriousfriction results.

The object of my inventionis to produce a very simple andinexpensivespring brake attachment, which may be applied to the shafts and anglerollers, which is adjustable so as to fit rollers arranged at diflerentdistances apart, and which is adapted to clasp the shafts in such amanner as to permit the usual endwise and the necessary rotary movementsof the rollers, but to prevent the rollers from rotating except when inactual contact with the table. v

To these ends my invention consists of cortainfeatures of constructionand combinaangle rollers, these being shown in their customary positionadjacent to the reciprocating inking table of a printing press. Fig. 2is a detail planview of the attachment embodying my invention. Fig. 3 isan end elevation, partly in vertical section on the line 33 of Fig. 2,showing also the application and Fig. 4 is a vertical section on theline 4;&

of Fig. 3. p

The angle rollers are of the usual kind and arranged in the customaryway, being carried by shafts 11 which have reduced ends 12 forming thejournals, these being hung in the slotted posts 13 on the press 14 inthe usual manner, and the journals 12 are free to slide for a limiteddistance in the posts. The angle rollers contact with the table 15,which is exactly the usual kind, and which has at its front edge aswinging contact bar 15 to first engage the rollers.

The rollers are usually arranged in pairs, and consequently I provide aspring brake attachment which is adapted to be applied to a pair of theroller shafts. In this attachment a pair-of upper shoes 16-and lowershoes 17 are used, which are adapted to clasp the shafts 11, see Figs. 3and 4, and as they are pressed together by a spring as described below,and the friction of the shoes on the shafts is sufficient to stop therotation of the shafts as soon as the rollers are out of contact withthe table. The shoes 16 and 17 are carried by upper and lower plates orbrackets 18 and 19, the former being bent downward in the middle, asshown at 20, so as to the better act as a guide for the connecting bolt21 which is fastened rigidly to the lower plate 19 and slides freelythrough the bent portion of the upper plate 18, the bolt having at itsupper end a head22 between which and the lower portion of the bend 20,in the'upper plate, is a spiral spring 23, which is coiled around thebolt and the pressure of which is sufficient to force the platestogether hard enough to cause the shoes 16 and 17 to press withconsiderable friction on the shafts 11, and thus when the shafts are setin motion by the table the shoes will stop them as soon as the tableleaves the rollers. It will be seen that the spring 23 may be made juststrong enough to have the desired effect on the brake shoes. The upperand lower plates 18 and 19 are slotted longitudinallynear the ends, asshown at 24, and fastening screws 25 project through the slots and intothe shoes 16 and 17, thus holding the shoes in place, and it will beseen that this arrangement enables the shoes to be adjustedlongitudinally in relation to the ice plates so that they may be made tofit properly on the roller shafts 11, which may be at differentdistances apart.

When the brake attachment is to be applied to a pair of rollers, thepairs of shoes are arranged the proper distance apart so that they mayfit nicely on the shafts of the rollers, and the head 22 of the bolt isthen grasped and the lower plate 19 with the shoes 17 turned at rightangles to the upper plate, as shown in Fig. 2, thus permitting the lowerplate and the lower shoes to be pushed downward between-the adjacentroller shafts, and the shoes 17 are then turned back parallel with theshoes 16 and permitted to spring upward against the shafts, after whichthe shoes 16 and 17 will clasp the two shafts as clearly 'illustrated inFig. 3.

By reference to Fig. 4: it will be seen that the upper shoes 16 arelonger than the lower shoes and the shoes 16 are longer than thelongitudinal movement or stroke of the rollers with which they areconnected, so that there is no danger of a shoe 16 dropping down on thejournal 12 so as to cause the shoe to prevent the necessary endwisemovement of the roller.

It will be seen that the attachment is very simple and inexpensive, thatit may be readily applied to the shafts of the rollers, and that it isan easy matter to adjust the tension of the spring 23 in such a way asto permit the rotation of the rollers and yet stop them as soon as thetable passes out of contact with parallel shafts, substantially asdescribed.

2. A device of the kind described, comprising an upper and lower plate,the upper plate having a depending middle bend, a springpressed boltsecured to the lower plate and slidable in the bend of the upper plate,and brake shoes carried near the ends of the two plates and adapted toclasp parallel shafts, substantially as described.

3. A device of the kind described, com prisingbpposite plates, a springfor pressing the plates together, and shoes carried by the plates andadapted to clasp parallel shafts, one shoe of each pair being longerthan the other, substantially as described.
